To solve the expression $\frac{2}{3} - (-\frac{3}{4})$, follow these steps:

1. Recognize that subtracting a negative number is the same as adding the positive equivalent. Therefore, the expression becomes: $\frac{2}{3} + \frac{3}{4}$

2. To add these fractions, they must have a common denominator. The least common denominator of 3 and 4 is 12.

3. Convert each fraction to have the common denominator of 12: $\frac{2}{3} = \frac{2 \times 4}{3 \times 4} = \frac{8}{12}$ $\frac{3}{4} = \frac{3 \times 3}{4 \times 3} = \frac{9}{12}$

4. Add the fractions: $\frac{8}{12} + \frac{9}{12} = \frac{8 + 9}{12} = \frac{17}{12}$

5. Simplify the fraction if possible. In this case, $\frac{17}{12}$ is already in its simplest form.

So, the solution is: $\frac{2}{3} - (-\frac{3}{4}) = \frac{17}{12}$
